Renewed .Tune 10, 1913. Serial No. 772,914.

maintaining the liquid entirely separate lrcm outside air, will act as a pump to automatically supply itsel'tl with liquid from a suitable source ot' nupply, to ycause the liquid to tlow through the machine, and to raise the liquid to a higher level tor convenience in ti'urther treatment-` and which can easily be taken apart and .the wearing surtaces properly located and adjusted.

ln the accompanying drawing. the ligure is a vertical section ol my iml'iroved machine, certain parts being shown in side elevation. v

lleterriner to the drawing, S7 indicates an outer cylindrical wall supported upon standards 2, and 8U indicates an inner cylindrieal wall. said walls being connected at:

their ends with casing heads Ell. 8S, and thus Vtol-ming a water jacket. lnto the space between these walls hot water is supplied t'roin a vessel l"t),'having an overflow pipe 121. by a pipe 122, which connects with a. ltittinnl 1223, which latter connects` with a pipe 121i, into which the water is driijcn by the impact of steam emerging troma nozzle )25. l `rom the pipe 124v the hot water llows into an annular pipe 95 between said inner and outer cylindrical walls titl, 87lloivirig therefrom by minute holes Slt'iuto said water jacket. From said jacket itl flows through holes U7 into an annular pipo 95%, which pipe connects with a pipe 12th connectingn with the pipe t22. lirculation is thus main-` tained through said jacket.

rlhe liquid to be treated is drawn in by an inlet openings; 92, which leads centrally through the cas-ine head 9i. ln the other casing' head 8P) is formed thc outlet. conduit 55),' connected with a pipe til, into which' is inserted a thermometer tlO. lo a suitable bearing' in said head 38 is mounted a. shat't 1.27, having thereon tight and loose pulleys t287 129. The inner vnd o't said shalt is screwed, as shown at 30. into one head of a drum Sil, the other head 84 rotating upon@ stud shat't ll projecting inwardly from the head lll. Said head 8l is provided with impeller vancs 85, which, in the rotary motion ot the drunn tend to draw liquid through the inlet 92 and propel it along the narrow annular space between the drum S3 and the inner wall Sti and out by the outlet.I 89. A washer -rlt surrounds the shat't 127, and, press-ing; against` said washer, is a collar 42 on said shaft, making a tight joint thereat. llall hearings elfl are interposed between stationary and movable parts around said shaft.

I claim '1. ln an apparatus of the character de- Scril etl.\tl1e combination of a cylinder having closed ends, means for maintaining a` eirculat ion of water around said cylinder, a drum within said cylinder also having closed ends and a cylindrical wall closely adjacent to the inner wall of the cylinder, means connected to said drum and passing through one end ot the cylinder tor transmitting rotary movement to said drum, said cylinder having an inlet: at the center of one end thereof, and the end ot the drinn adjacent to said latter end lhaving' thereon impcller vanes t'or impelling liquid to cause it to pasis between said drum and cylinder wall, the other end ot the cylinder beiner provided with an upwardly directed outlet conduit.

2. l'n an apparatus of the character described, the combination of a cylinder having; closed ends, means for maintaining a circulation of 'ater around Said cylinder, a drum within said cylinder also having closed ends and a cylindrical wall closely adjacent to the inner wall of the cylinder, means connected to said drum and passing through one end ol' thc cylinder for transmitting rotary movianent to said drum, one end of said cylinder being removable and formed with an inlet opening, and provided with means vt'or rotate. ily and removably supporting.r the correspondiug end ot the drum therenin the other end ot' the cylinder beiner provided with an outlet conduit, one end of the drum being provided with impelleizvanes causing' the liquid to pass between the drum and the inner wall ot the, cylinder.

3. in an apparatus ot the character described` the combination of a cylinder having closed ends-i. means for maintainingr a circulation ot' water around said cylinder, a druzn within said cylinder also having,r closed ends and a cylindrical wall. closely adjacent.

to the inner wall of the cylinders means oonneeted to said drum and passing through one -end of the cylinder for transmitting rotary movement to said drum, one end of the eylinclerbeing removable una having a cenmovably and rotatably supporting the corresponding end of the drum, said end being provided with impeller 'vanes forimpellng the liquid, to the other end of the'eylinder, said cylinder being;- formed with an outlet conduit at said other end.

In testimony whereof I have hereunto set my hand in thepresence of tWo subscribing 15 Wlt-nesses.
